)))perfect I will do that in the meantime

@Phaedrux Thanks for the help once again and sigh... good luck to me to try to get another bltouch during a pandemic....

@Phaedrux Bro thanks so much for your help I feel like a super noob and dumb. So I realized that short is not on my other bltouch so hence it defective. I put my other bltouch from my other machine again and wired up to test and z stopped so I guess I will have to purchase another bltouch because it looks like the signal wire is shorted to ground.

@Phaedrux I think your right I put two pieces of bare wire and held them together once I let go the z motor actually stop so I your right there has to be something wrong with the wire or so...... Not sure how to trouble shoot it at least on the pcb side of the bltouch i get continuity between grounds and the signal wire on the pcb i don't think this is right but looks like a short I couldn't find a schematic to see how the bltouch pcb wiring looks like?

@Phaedrux

1. Yes
2. Yes
3. Yes
4. Yes
   5.Yes a gentle touch will cause the pin not to retract on it own it just pops right back out applying a bit more push causes it to retract and go into a flashing red alarm state.
5. With a gentle touch or the alarm state does not stop the z axis movement.

Thanks for your help I really do appreciate it all your doing for me.

@Phaedrux Yes it works fine on my other machine but it not a duet2 wifi it a marlin based system.

@Phaedrux after applying a g30 i had the pin press the bed slowly but it did not retract i pushed a bit more and it retracted into alarm state

@wepaking If i pull the pin manually and push it back in it doesnt retract automatically and it also does not go into alarm either.

@Phaedrux Send a M401/M402 command works with retract and deploy but if i touch the bltouch gently when it is deployed it will go into an alarm state.

@Phaedrux I cant seem to attach the images

I gently put my finger on the probe and it does not retract if I push more then it goes into alarm mode using the M280 P3 S10 I1 OR S90 same thing occurs I wil also look into the link you provide thanks as well.
